PROFILE

Datong Sun

Worked on Kong/atc-router and Kong documentation repositories, focusing on build system simplification and developer experience. Removed the Bazel build system and relaxed Cargo dependency pinning, streamlining builds and improving CI reliability using Rust, Shell, and Cargo. Enhanced documentation for Kong/docs.konghq.com by clarifying IP address comparison semantics in the expressions language, reducing ambiguity for users configuring access-control logic. Later, restored and expanded documentation for raw string literals in expressions on Kong/developer.konghq.com, enabling easier regex usage without escaping complexity. Demonstrated skills in build system management, dependency management, and technical writing, with a focus on maintainability and onboarding efficiency.
